You're getting a nice bright trace, your high voltage is fine. No need to mess with the high voltage points.

Everything you need to worry about should be under 300V, 260V is the highest my 2120 has apart from the HV to the tube. Zemax Torrent Crack Windows.

If you have a supply problem then there can be all kinds of weirdness.

I don't know how similar yours is, but on my 2120 the sweep circuit needs quite a few rails, the +5V, +/-12V and +24. You can isolate the sweep circuit from the CRT horizontal drive circuit. Put the scope in X*Y mode and apply a voltage to the channel 1 input.

In X*Y there is no sweep. The dot should move right or left depending on whether it is + or - and should not move vertically. If you center the dot and set the scope to 1V/div and apply -5V to the input the dot should move all the way to the left without moving vertically, +5V will make it go right.

If this all seems normal than the problem is in the sweep circuit, not the CRT horizontal drive. If the dot moves vertically at all on channel 1 then it is a CRT horizontal drive problem. You can repeat the same test on channel 2, however the dot should move vertically. If there is no movement then that channel is dead. The channel 2 problem was likely operator error, might have blown the vertical amplifier circuit on that channel. Likely not that big of a deal.

Hard to say about the sweep problem. Could just be aging components like capacitors. I don't know how different the sweep circuit is on the 2160, my 2120 doesn't have the delayed time base. It is worth keeping around if you do get another scope, having a working one is really helpful for repairing a broken one. You learn a lot by repairing them, you learn how they work and a lot about troubleshooting in general. So far I have 3 that I have repaired, a B&K Precision 2120 20Mhz 2 channel, a Tektronix 2221A 2 channel 100Mhz and a Hitachi V-1150 4 channel 150Mhz. I got them in that order, all cheap and worked my way up to having 2 pretty nice scopes for less than $100 invested.

This is an awesome guide put out by Tektronix, but the principles apply to all analog oscilloscopes. If I lived near you I'd take it, I don't have one with that component tester.
